				<div class="class-description"><p>Texture library for <a href="RectAreaLight.html">RectAreaLight</a>. This class holds the LTC BRDF data
in data textures for further use in the renderer.</p>
<p>Reference: Real-Time Polygonal-Light Shading with Linearly Transformed Cosines
by Eric Heitz, Jonathan Dupuy, Stephen Hill and David Neubelt. <a href="https://github.com/selfshadow/ltc_code/" target="_blank" rel="noopener">Code</a>.</p>
<p>NOTE: This is a temporary location for the BRDF approximation texture data
based off of Eric Heitz's work (see citation). BRDF data for
<code>RectAreaLight</code> is currently approximated using a precomputed texture
of roughly 80kb in size. The hope is to find a better way to include
the large texture data before including the full RectAreaLight implementation
in the main build files.</p></div>
